so, how do you even cache data that changes all the time? its a tricky one, honestly.

Hey everyone, I'm working on a system where some data changes fast, like every few seconds. We want to cache this data to cut down on load for the main database, but also make sure users aren't seeing old info for too long. What strategies or tools have you found helpful for caching data that has a really short TTL or needs updates often? Looking for practical advice.
